CORRUGATED RIDGE-CAAPPING FOR BUILDINGS.

SPECIFICATION forming part of Letters Patent No, 365,096, dated June 21,1887.

Application tiled October' Q7, 1886.

T0 all whom it may concern:

Be it known that we, W iLLLxM H. Fownns and BENJAMIN F. Powers, ofCleveland, in the county of Cuyahoga and State of Ohio, have invented acertain new and Improved Corrugated Ridge'Capping for Buildings,consisting of two sections or parts secured together by nuts or bolts;and We do hereby declare that the following is a full, clear, andcomplete description thereof.

The nature of our invention relates to a crimped or corrugated angularstrip of sheet or plate metal with a. tubular or cylindrical ridgeriveted to the junction of the angle of the sheet and extending theentire length of the capping. The attachment of the tubular ridge to theapex or junction of the angle is so made as to admit of the expansionand contraction longitudinally ot ridge-capping sections. The angularstrip is crimped along the ridge or point of the angle and sides toprevent the sheet from cracking or breaking, while the tubular ridgeinsures strength and stability to the angular sheet, as hereinafterfully set forth.

Figure l is a top view of the ridge-capping; Fig. 2, a side view, andFig. 3 is a transverse section.

Like letters of reference refer to like parts in the several views.

The ridgecapping consists or" two parts or sections-the corrugated andangular cap A and the tubular ridge B-which are secured together byscrew-bolts or rivets C, Figs. l and 2. The ridge B forms a tube alongthe. entire length of the capping, the ends of which are united by alap-joint'connection, or otherwise secured together. The purpose of thetubular ridge is to give strength to the cap or capping A, which isessential when the entire root is of iron and a large or Wideridge-capping required. In a slate or tlat sheet roof it is also ofmaterial advantage and forms an ornamentation to the roof-ridge.

By making the capping first separate from the ridge B the crimps D canbe pressed into the top part of the capping, (which cannot be done incase the ridge B and capping A are in one piece,) which is of materialadvantage in preventing the plate from buckling up in Serial No.217,353. (No model.)

making or when in use. Along the sides of the capping are formed crimpsor corrugations E. These corrugations may be changed to correspond withand adapted to the forni of the roof on which is to be theridge-capping, as indicated at F, which represents a part of ametal-plate roof, Fig. 3. As the ridge B is of a separate section fromthe capping A, the expansion and contraction transversely by climaticinfluence of one section does not in use al'fect the integrity of theother. As the rivets or their equivalents pass through slots in thesections A and Bin line with the capping, the sections are securedtogether, and-also admit by means of the slots a free expansion andcontraction longitudinally of the sections. The tubular form of theridge admit of its extension and contraction longitudinally by reason ofthe yielding attachment and at right angles Without affecting thecapping A, and the crimps at D relieve the sheet from buckling up whenthe corrugatioiis E and crimps D are pressed out on the sheet. Thecrimps D and corrngations E compensate or so neutralize the extensionand contraction of the sheet as to prevent it cracking or buckling up bythe strain ot' the Weather to which it is subjected. This is essentiallythe case when la large metallic surface is exposed.

In case of injury to one part ot' the ridgecapping, the injured sectionmay be removed and a new one substituted Without displacing the entireridge-capping. This construction admits of the ridge-capping being madeof one continuous unbroken length by inserting a series of tubularridges B, one into the other, and lapping the capping A onto each otherin such way as to break joints at connections with the ridges B andcapping A- that is to say, the lapping of the capping need not be intransverse line with the connection of the tubular ridges.

Vhat We claim as our invention, and desire to secure by Letters Patent,is-

1. A metallic ridge-capping for buildings and other similar purposes,consisting of the corrugated section A, in combination with the tubularridge B, constructed as described, and connected together in the mannersubstantially as set forth.
